@b3e72378 Ubuntu is a solid choice, I believe you have to add some 32-bit PPAs to install Steam, pretty easy to google.

I had some hardware compatibility issues with Garuda on a budget PC build.

I had excellent out of the box success with Drauger OS, comes with Steam and other gaming programs.

You can set it all up on Arch Linux. I was able to get it all installed as quite the Linux noob. Arch is by far the lightest distro to be running in the background.
